Abstract

The utility model discloses a smoke discharging strobe frame structure, mainly including a buckling device, a control module, a buffer air pressure rod, a tension spring, two torsion springs and a strobe and an upper frame; the torsion springs are arranged on the two ends of the axis frame; with the help of the buffer air pressure rod, the torsion spring and the tension spring, the strobe can lower the strength in the opening; when the disaster takes place, the strobe can be rapidly opened to discharge the thick smoke; because one half surface of the strobe is welded with a M-shaped plate clashing the other glue strip adhered on one half side surface of the upper frame and the glue strip has an appropriate deforming degree, the device can be started and closed more rapidly; when the strobe is closed, the hermetic state can be maintained; different kinds of plate materials can be put in the strobe, exerting a beautifying effect on the ceiling.

Description

Smoke evacuation gate frame structure

Technical field:

The utility model relates to a kind of fume extractor, refers to a kind of being installed on the ceiling board especially, the smoke evacuation gate framework that discharges as dense smoke during for confined space breaking out of fire accident.

Background technique:

High building stands in great numbers now, general building then is an indispensable equipment for public fire protection equipment, requiring in fire codes all needs to be provided with the smoke evacuation gate in public arena, building and high buildings and large mansions, right in separating single independence, independent or a smoke exhaust port that is communicated with or an equipment of discharging fume gate also need be arranged; Seeing commercial building building, all is the mode institute construction with exposed conveying appliance, and therefore, how the smoke evacuation gate in separate space and public space can reach attractive in appearance and not lose its effect, is dark problem of grinding.

Set up complete wall in high buildings and large mansions in this way, and smoke evacuation gate framework all is to expose pattern, and body frame can produce the gap with gatehouse, though this meets the demand of fire codes, so this can't reach the demand airtight with maintenance attractive in appearance.

As existing smoke evacuation gate framework, please consult Fig. 1-shown in Figure 3 simultaneously, the weldering on the inboard longitudinal wall face of E-4 face of this main frame 1 is provided with a fixed plate 10, be fixed in wherein for button system device, and a L shaped plate (11,11 ') is established in weldering on E-1, the inboard longitudinal wall face of E-2 face, and is stained with an adhesive tape 12 in fixed plate 10 and L shaped plate (11,11 ') bottom surface; Moreover this gate 2 is the grooved sheet metal of a bending forming, and when closing, its gate 2 one demifacet top and adhesive tape 12 resist; Other is the person, need during because of turn leave certain interval X in gate 2 another demifacets with body frame 1, make it to be rotated, its disappearance is that floor and floor gap are installed several smoke evacuation gate systems, because of the smoke evacuation pipeline of smoke evacuation gate is all contacted to a large-scale induced draft fan, if start this floor smoke evacuation gate system during the breaking out of fire of one floor, if the smoke evacuation gate of the floor that all the other do not start leaves gap X, pneumatic benefit in the time of can't keeping air tightness then can influence smoke evacuation during its smoke evacuation, make it to slow down the speed of smoke evacuation, though, can't reach beautifying of the environment demand airtight with maintenance though known smoke evacuation gate framework meets the requirement of fire codes.

The inventor wish to utilize the one chip gate for base material design a kind of can be embedded on the ceiling board as fume extractor, can mode allows fume extractor open or to close more to save time fast to reach when action, and the effect that beautifies is arranged when reaching not enabled, opened smoke-discharging gate rapidly when taking place as fire by this, reach the dense smoke that to produce and discharge, to meet the demand of fire codes.

The model utility content:

Technical problem to be solved in the utility model is: at the above-mentioned deficiency of prior art, a kind of smoke evacuation gate frame structure is provided, what gate can do that 90 degree open or close when it started turns to lift, and make when disaster takes place can be rapidly will the smoke evacuation gate opening, to meet the requirement of fire codes.

In order to solve above-mentioned skill problem, the technological scheme that the utility model adopted is: a kind of smoke evacuation gate frame structure, it consists predominantly of a body frame, one gate, one button system device, one control module, one cushion gas pressure bar, one tension force extension spring and two torsion springs, weldering is provided with a fixed plate on this body frame inner edge one side longitudinal wall face, weldering is provided with L shaped plate on its left and right sides longitudinal wall face, be stained with an adhesive tape on this fixed plate and the L shaped plate base plane, be characterized in: be stained with another adhesive tape on half lateral plane of described body frame, one demifacet edge joint weld of described gate is provided with a ㄇ shape plate, and the ㄇ shape plate of this gate and another adhesive tape of body frame are conflicted mutually.

Compared with prior art, the utility model has the advantages that: the torsion spring of this smoke evacuation gate framework is arranged at the two ends of bracing strut, makes gate can slow down the strength that presses down of gravity acceleration when opening; Cushion gas pressure bar and torsion spring can allow gate face upward, the bow action of turn when opening; In addition, gate is the metal material of a bending forming, and the adhesive tape that is provided with in this body frame and gate has suitable distortion nargin, can more rapidly and close when action, and can keep airtight state when closing; This gate can be inserted various sheet material, and it has the effect that beautifies to ceiling board.
